In fact, NCT7802Y seems to be use to monitor voltage and control fan too.

In this thread about NCT6791D support for linux
http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039688.html [^]

they explain that the "nct6775" driver is compatible with NCT6791D chip.

and they had: > But i don't understand why there is also the NCT7802 chip
the answer: The board supports up to seven fans, so they need more than one chip
to monitor and control all those fans. Good news is that it suggests that
ASUS may move away from the idea of using multiplexers to switch between
fans.

The NCT6791D is now fully supported by the development beta. You can get a preview by contacting me by email.
What I cannot find is the NCT7802Y on this motherboard :-(

Thank alfredo for the progress.
Fan control fully work.i can controle independently and on all the range of rpm for all the 5fans.
Temp sensor is wrong.
For rpm sensor. 4/5fans indicate right rpm. For the last fan, when it rise to 100% and all other to 0%. All fans rise up from 0 rpm to 255rpm.strange.

I set my fans up now, and they work great for me too (I have a Z87-A). I have the same thing with the last fan.

The CPU temp seems correct, but it doesn't use the digital sensor that reacts to core temps instantly, which is good for me as my fans kept spinning up and down with the AI Suite 3 due to that.

The individual core temps seem to be all over the place (i.e. not working).

Hello Truga, which beta did you test? Individual CPU Core Temperatures should be reporting fine now.
